CHURN.

SPECIFICATION forming part of Letters Patent No. 454,750, dated June 23,1891. Application filed October 13, 1890. Serial No. 367,960. (Nomodel.)

To aZZ whom it may concern.-

Beit known that I, OLIvER LINEBARGER, a citizen of the United States,residing at Council Bluifs, in the county of Pottawattamie and State ofIowa, have invented certain new and useful Improvements in Ohurns; and Ido hereby declare that the following is a full,

clear, and exact description of the same, referonce being had to theannexed drawings, making a part of this specification, and to the let=ters of reference marked thereon.

Figure 1 of the drawings represents an elevation of my improved churnwith a portion thereof in broken section; Fig. 2, a similar view atright angles to that of Fig. 1; Fig. 3, a detail view, in perspectiveand on an enlarged scale, of the dasher.

The present invention has for its object to provide a churn that will besimple in construction and easy of operation, the dasherblades being ofsuch construction as will more effectually agitate the cream when inmotion, and thereby render them more effective, and also imparting tothe dashers a motion on a line describing an ellipse, each dasherpassing alternately over the other and having both an up-and-down and alateral motion, thereby providing means for securing a perfect agitationof the cream and rendering the churn additionally effective in itsoperation. These several objects I attain by the constructionsubstantially as shown in the drawings, and hereinafter described andclaimed.

In the accompanying drawings, Arepresents the body or cylinder of thechurn, preferably of glass; but any other material may be used, as founddesirable, said cylinder being of any suitable height and diameternecessary to hold any given quantity of cream. The cylinder, as abovedescribed, rests on a support B, provided with eyebolts a, with whichdetachably engage the hooked ends of clamping-rods O, which engage withopen slots 17 in ears 0, extending from the edge of the cover D. Theupper ends of the clamping-rods C are screwthreaded, as shown at d, withwhich engage thumb-nuts e for drawing the cover D down tightly againstthe edge of the churn-cylinder A, as shown. In order to disengage theclamping-rods from the open slots, so that the cover can be removed, itis only necessary to loosen the thumb-nuts and press the rods outlaterally from engagement with the open slots, when the cover, with itsattachments, hereinafter described, can'be removed for cleaning, or bysimply loosening the thumb-nuts the churn-cylinder can be removed, asdesired. Upon the inner sides of the support and cover, respectively,are elastic cushions E F, so that when the cylinder is of glass orsimilar fragile material the danger of breaking it by tightening thecover thereon is Wholly removed, and, further, the cushion on the covermakes a tight joint between it and the edge of the churn-cylinder.

7 Connected to the cover D are two brackets G H, extending upright anddisposed parallel with each other, and between these brackets is asprocket-wheel I, connected to a shaft f, which has its hearings in theupper ends of said brackets and operated by a crank-handle J, suitablyconnected to one end of the shaft, which projects out beyond the side ofone of the brackets, as shown in Fig. 2. Engaging with the teeth uponthe sprocket-wheel I is a sprocket-chain K, which also engages with theteeth of a small sprocket-wheel L upon a small shaft g, which also hasits hearings in the sides of the brackets. To the projectlng ends of theshaft g are pitmen M, and to these pitmen are adjustably connected thedashershafts N, having upon their lower ends the dasher-blades Oone ormore upon each shaft, as found desirable. In the present instance I haveshown two upon each shaft, which have perforations h and angular orinclined sides h, or, in other words, in shape of an 1nverted V, asshown more clearly in Fig. 3. The dasher-blades are so connected to theshafts as toproject horizontally from the inner sides thereof and theapex of the angle formed by the two sides of the blade being uppermost.

It will be seen by reference to Fig. 2 of the drawings that the pitmenare so connected to the small shaft that their free ends will extendparallel, but in opposite directions, whereby the dashers will have analternating motion; or, in other words, when one is on itsdownwardstroke the other will be on its upward stroke.

The dashers, as will be noticed by reference to Fig. 1 ofthe drawings,do not move in a vertical direction, but at an angle, each dasher at itslower end passing in turn over the other and each describing in itsmovement an ellipse, as indicated by the arrows, thereby having acompound motion that is peculiar in itself and especially adapted to achurn dasher where an increased and powerful agitation of the cream isdesired with comparatively little exertion by the operator.

The holes in the cover D are of sufficient size to allow of thedasher-shafts through which they pass to assume the angle shown in Fig.1 and to operate as hereinbefore described, and the shafts at theirupper ends have a series of holes i to admit of their adjustability inlength to adapt them to the amount of cream in the churn-cylinder.

The dasher-blades herein described are dif ferent in construction fromthose in common use in that they have open ends 76 to allow the cream tobe forced out therefrom upon each downward stroke of the dasher.

A further and important feature of the invention is the position theblades assume with relation to the dasher-sha-ftviz., projecting of theblades from the shaft upon one side only, and that the inner side,thereby enabling the dashers to have a greater sweep than whenprojecting from both sides and more efiectually gathering and agitatingthe cream from the center of the churn. It will be further noticed thatthe lower ends of the shafts N are extended in width for the purpose ofpresenting a wide surface or wall R to the cream. Now upon the downwardstroke of the dashers, when the under sides of the blades are brought incontact with the cream, the

latter is forced laterally against the Wall R, and what does not passthrough the perforations of the blades is forced out through the openends 7t. Thus the peculiar construction of the dasher-blades and theiropen ends coact with the widened portion of the dashershafts at theirlower ends.

The above features of construction, in addition to the location of theblades upon the inner side only of the shafts, render them moreeffective on the cream, causing it to be kept in the greatest possiblemotion in connection with the peculiar motion of the dasher-shafts, thecream being agitated uniformly at both the top and bottom and at thecenter, thus bringing the churning to a success ful end in a very shortspace of time and with comparatively little labor on the part of theoperator.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

In a churn, the combination of the dashershafts N, extended in width attheir lower ends to form walls R, and the inverted-V- shaped perforateddasher-blades 0, having open ends 70 and extending from the inner sidesonly of the shafts, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

OLIVER LINEBARGER.
